External auth support
Should be fairly easy since users are entirely decoupled from the rest.
- LDAP with https://github.com/jmerriweather/exldap or https://github.com/minijackson/paddle
- OAuth2 with https://github.com/scrogson/oauth2 (you could login with your Mastodon account!)
- https://github.com/ueberauth/ueberauth for generic things
